Description

Sensor cover

The present invention relates to a sensor cover, and more particularly to a sensor cover to be wrapped when a biological sensor used by being attached to a living body is used.

Conventionally, a stick-on type biosensor (patch sensor) that is used by being attached to a living body and acquires biological information such as body temperature and an electrocardiographic signal is known. When such a stick-type biosensor is used in a hospital, for example, the biosensor is stuck to the living body with a double-sided adhesive sheet or the like in order to prevent stains due to antiseptic solution or the like, and further, dressing is performed from above. A film or surgical tape is attached to cover the biosensor (see, for example, Patent Document 1).

Japanese Unexamined Patent Publication No. 1-201128

By the way, when the above-mentioned stick-type biosensor is repeatedly used (reused), a double-sided adhesive sheet or the like is stuck on the bottom surface of the biosensor and stuck on the living body (skin) from above. It is necessary to attach a dressing film cut to an appropriate size, and on the other hand, after use, it is necessary to peel off the dressing film and dispose of it, and also peel off the double-sided adhesive sheet from the biosensor to collect the biosensor.

Therefore, it takes time to attach / detach the biosensor, dressing film, etc., which is not easy to use. Further, when a relatively flexible material such as urethane is used as the exterior material of the biosensor, the exterior material may be damaged when the dressing film or the like is peeled off.

The present invention has been made to solve the above problems, and is a sensor cover to be wrapped when a biosensor used by being attached to a living body is used, and is a biosensor (particularly an exterior body) at the time of replacement. It is an object of the present invention to provide a sensor cover that can be easily replaced while preventing deterioration and damage.

The sensor cover according to the present invention has an upper cover film and a lower cover film having at least one side connected to each other, and is provided on a cover film formed in a bag shape capable of accommodating a biological sensor during use and an outer surface of the lower cover film. An adhesive sticking member, a sensor mounting member provided on the inner surface of the lower cover film to attach the biosensor in close contact with the lower cover film, and a sealing member that closely closes the edge of the opening of the cover film. It is characterized by having and.

According to the sensor cover according to the present invention, first, the cover film has an upper cover film and a lower cover film in which at least one side is connected, and is formed in a bag shape capable of accommodating a biological sensor at the time of use. The biosensor can be easily put in and taken out of the film (between the upper cover film and the lower cover film). Next, since the sensor mounting member for mounting the biosensor in close contact with the lower cover film is provided on the inner surface of the lower cover film, the biosensor can be easily mounted inside the lower cover film (inside the cover film). Can be done. Further, since the adhesive material does not adhere to the outer surface of the biosensor, it is possible to prevent the outer body of the biosensor from being deteriorated or damaged when the cover film is removed. Further, since the sticking member having adhesiveness is provided on the outer surface of the lower cover film, the biosensor can be easily stuck to the living body via the cover film (lower cover film). Further, since the cover film has a sealing member that closes the edge of the opening of the cover film in close contact with the cover film, the cover film can be easily sealed. Then, it is possible to prevent the infiltration of the disinfectant solution and the like.

As a result of the above, according to the present invention, in the sensor cover to be wrapped when using the biosensor attached to the living body, it is simple while preventing deterioration or damage of the biosensor (particularly the exterior body) at the time of replacement.

Further, in each figure, the same elements are designated by the same reference numerals, and duplicate description will be omitted.

(First Embodiment)
First, the configuration of the sensor cover 1 according to the first embodiment will be described with reference to FIGS. 1 to 4. Here, an example is obtained in which the present invention is applied to a stick-on type temperature sensor (deep thermometer) 101 (corresponding to the biological sensor described in the claims) which is attached to a living body and measures the core body temperature of the living body. I will explain. FIG. 1 is a plan view of the sensor cover 1 during use. FIG. 2 is a cross-sectional view taken along the line II-II of FIG. FIG. 3 is a cross-sectional view of the sensor cover 1 before use (for example, at the time of factory manufacturing, sales, storage, etc.). FIG. 4 is a cross-sectional view showing the configuration of the stick-on type temperature sensor 101.

In this embodiment, as the stick-on type temperature sensor 101, a two-heat flow type deep thermometer equipped with a pair of

thermal resistors

1015 and 1016 and two pairs of

thermistors

1011, 1012 and 1013, 1014 was used. .. As the two-heat flow type deep thermometer, for example, those described in International Publication No. 2019/225532 and the like can be preferably used.

The sensor cover 1 is a cover to be wrapped when the temperature sensor 101 used by being attached to a living body is used. The sensor cover 1 is a disposable type cover. The sensor cover 1 has a function of being easily replaced while preventing deterioration or damage of the stick-on temperature sensor 101 (particularly the exterior body 1010) at the time of replacement.

Therefore, the sensor cover 1 mainly includes a cover film 10 having an upper cover film 10a and a lower cover film 10b, a sticking member 20, a sensor mounting member 30, and a sealing member 40.

The cover film 10 has an upper cover film 10a and a lower cover film 10b having at least one side connected to each other, and is formed in a bag shape capable of accommodating the temperature sensor 101 when in use. In the present embodiment, the upper cover film 10a and the lower cover film 10b are each formed into a substantially rectangular shape with rounded corners, and two intersecting sides (the left side and the lower side in the example of FIG. 1) are connected. The other two sides are open (form). As the material of the cover film 10, for example, PET having waterproof property is preferably used.

On the outer surface of the lower cover film 10b, a sticking member 20 having adhesiveness for sticking the sensor cover 1 to the living body while wrapping the temperature sensor 101 is provided (sticked). As the sticking member 20, for example, a double-sided adhesive material for living organisms composed of silicon or polyethylene (PE) and an acrylic adhesive material is preferably used. Further, the sticking member 20 is formed in the form of a substantially rectangular sheet whose corners are chamfered, for example.

On the other hand, on the inner surface of the lower cover film 10b, a sensor mounting member 30 for mounting the sticking type temperature sensor 101 in close contact with the lower cover film 10b is provided (pasted). The sensor mounting member 30 is provided so as to face the sticking member 20 with the lower cover film 10b interposed therebetween. The sensor mounting member 30 is an adhesive member having adhesiveness, and for example, a double-sided adhesive material composed of polyethylene (PE) and an acrylic adhesive material is preferably used. Further, the sensor mounting member 30 is formed, for example, in the shape of a substantially rectangular sheet with rounded corners.

A sealing member 40 is provided at the edge of the opening of the cover film 10 to closely close the edge of the opening of the cover film 10. The sealing member 40 is an adhesive member having adhesiveness, and for example, a double-sided adhesive material composed of polyethylene (PE) and an acrylic adhesive material is preferably used. Further, the sealing member 40 is formed in a substantially L-shaped sheet shape, for example.

With the configuration as described above, the upper cover film 10a, the temperature sensor 101, the sensor mounting member 30, the lower cover film 10b, and the sticking member 20 are arranged in layers at the time of use.

Here, in order to reduce the variation in the thermal resistance value and improve the temperature measurement accuracy (estimation accuracy of the core body temperature), the thermal resistance value of the lower cover film 10b is larger than the thermal resistance value of the sticking member 20. It is preferable that it is set so as to be. In particular, the thermal resistance value of the lower cover film 10b is set to be larger than the total value (additional value) of the thermal resistance value of the sticking member 20 and the thermal resistance value of the sensor mounting member 30. preferable.

Here, for example, as shown in [Table 1], when the thickness of the lower cover film 10b is 300 μm, the thickness of the sensor mounting member 30 is 50 μm, and the thickness of the sticking member 20 is 50 μm, the three-layer thickness tolerance. Is ± 20%, and the variation in thermal resistance value can be made smaller than in the example of [Table 2] described later. That is, by increasing the thickness of the lower cover film 10b, which has little variation in the thermal resistance value, it is possible to reduce the variation in the total thermal resistance value of the three layers. Therefore, the correction when estimating the core body temperature can be performed more accurately.

On the other hand, for example, as shown in [Table 2], when the thickness of the lower cover film 10b is 15 μm, the thickness of the sensor mounting member 30 is 50 μm, and the thickness of the sticking member 20 is 50 μm, the tolerance of the thickness of the three layers is large. It becomes ± 40%, and the variation in the thermal resistance value becomes larger than that in the example of [Table 1] described above.

Considering the above-mentioned thickness tolerance (that is, variation in thermal resistance value), if the thickness of the lower cover film 10b is a combination having a larger thermal resistance value than the sensor mounting member 30 and the sticking member 20 (double-sided adhesive material), It can be selected in the range of 30 μm to 2000 μm.

Next, with reference to FIG. 3, the configuration of the sensor cover 1 before use (for example, at the time of factory manufacturing, sales, storage, etc.) will be described. FIG. 3 is a cross-sectional view of the sensor cover 1 before use.

The sensor cover 1 before use includes a first peeling member (separator) 51 that is detachably attached to the attachment member 20 so as to cover the above-mentioned attachment member 20 (double-sided adhesive material for living organisms), and a sensor attachment member. The sealing member so as to cover the second peeling member (separator) 52 detachably attached to the sensor mounting member 30 so as to cover 30 (double-sided adhesive material) and the sealing member 40 (double-sided adhesive material). It is provided with a third peeling member 53 (separator) that is detachably attached to 40. Instead of the second release member 52 and the third release member 53, for example, a silicon-based release agent may be applied to the inner surface of the upper cover film 10a.

That is, the first peeling member 51, the second peeling member 52, and the third peeling member 53 are the adhesive surfaces of the sensor cover 1 (attaching member 20, sensor mounting member 30, sealing member 40) when the sensor cover 1 is not used. It is a member that can be attached to. The first peeling member 51, the second peeling member 52, and the third peeling member 53 are pulled from the adhesive surface (attaching member 20, sensor mounting member 30, sealing member 40) of the sensor cover 1 when the sensor cover 1 is used. It will be peeled off.

When using the stick-on type temperature sensor 101, first, the first peeling member 51 is peeled off, the temperature sensor 101 is stuck to the sensor mounting member 30 (double-sided adhesive material), and then the second peeling member 52 is attached. After peeling, the opening of the cover film 10 (between the upper cover film 10a and the lower cover film 10b) is sealed with the sealing member 40, and then the third peeling member 53 is peeled off to form the cover film 10 (sensor cover 1). The wrapped temperature sensor 101 is attached to a living body (skin).

Then, the temperature of the living body (core body temperature) is measured, that is, after using the stick-on temperature sensor 101, first, the temperature sensor 101 wrapped in the cover film 10 (sensor cover 1) is placed on the living body (skin). Next, the opening of the cover film 10 is opened, the temperature sensor 101 is peeled from the sensor mounting member 30 (double-sided adhesive material), and the temperature sensor 101 is collected.
